To all whom it may concern.-

Be it known that I, JENNINGS ScoTT Mc- COMB, a citizen of the United States, and resident of Dobbs Ferry, in the county of l'Yestchester and State of New York, have made certain new and useful Improvements in Desk Attachments, of which the following is a specification, takenin connection with the accompanying drawings.

This invention relates to desk attachmerits and relates especially to attachments for roll top oflicedesks by Which a special top or table is provided of suitable height for use when a person is standing, suchtop being suitable for book-keeping and other purposes and being arranged so as to fold up and be securely inclosed in a'suitable casing whennot in use.

In the accompanying drawings showing an illustrative form of this invention and in which the same reference numeral refers to similar parts in the several figures, Figure 1 is a side View of a desk showing the attachment in operative position, the casing and the closure for said casing being shown in section. Fig. 2 is a side section showing the attachment inclosed in the case. Fig. 3 is a partial detailshowing the collapsing of the leg and support; and Fig. 4 is a front View.

In the illustrative embodiment of this invention shown in the drawings, a desk 'of the general roll-top type is indicated having the top 26 to which the side pieces 1 are secured so as to properly support the desk cap 2, as is usual. The casing 4 Which is part of the attachment is secured upon the cap and lirmly held in position by a depending flange 28 at the back of the casing which passes behind the rear edge of the cap and by suitable fastenings, whichmay be in the form of pivoted buttons 27 adapted to engage the front edge of this cap member. .The casing as indicated may be provided with the door 6 havingthe handle 9 and secured by the hinge 7 to the flap 5, a section of the top of the casing of the desired width being secured thereto by the hinge 8 which may extend throughout the entire .width of the casing if desired. The base 3 of the casing is preferably provided with suitable guides Which may be in the form of slotted metal plates 10 as indicated, to roperly engage and support the reduced nec s of the studs 11 secured to the top section 12 of the table 13. The table is also referably provided with a lower section or eaf 17 which may have a retaining ledge 18,

this leaf being secured to. the main portion of the table by a suitable heavy hinge 14 which may extend its entire width, if desired, and which operates to rigidly su port the table sections in proper position wli en extended as indicated in Fig. 1.

The lower end of the table may be supported by legs '19 secured thereto ots 20 and connected at their lower ends by the rod 22 whose'ends may project slightly beyond the outer surfaces of the le s. The supports 21 are preferably ivote by the pins 29to the legs adjacent t eir lower ends and may be provlded with suitable slots 23 to accommodate the ends of the rod 22, these slots having preferably a generally curved contour as indicated and being of sufficient depth to extend through to' theouter face of the support, although this is not necessary in all cases. Adjacent the lower ends of the supports they are rigidly connected by the stay 24, their lower ends provided with suitable'eushionlng material in the form of tips 25.

In the extended position indicated in Fig. 1, the table is firmly supported at its lower edge by the legs and supports which are prevented from buckling outward by the engagement of the ends of the rod with the slots 23, the upper portion of the table being supported by the rigid engagement of the heads of the studs 11 with the ends of the metallic guideways. The various portions of this attachment may, of course, be readily folded toge ther, the supports folding simultaneously about the corresponding leg members and the leg members folding. upward against the leaf 17, a suitable s ring clip 15 or other fastening being preferably provided to engage the rod 22 and hold the parts in igs. 2 and 3.

the closed position indicated in B The leaf 17 may thereupon be folded back ward under the table 13 so that the parts may all be pushed within the casing, the studs 11 moving backward along the slotted guides so that all the parts are completely inolosed within the casing 4 when the door 6 is closed as indicated in Fig. 2. The provision of suitable handles or straps 16 adjacent the lower end of the table allows the con venient withdrawal of the parts from the easing when it is desired to use them.

Having described this invention in connection with an illustrative embodiment thereof, to the details of which disclosure it is, of course, not to be limited, what is by the p1v.

being preferably engaging said claimed as new .and what is desired to be secured by Letters Patent is set forth in the appended claims,
